Library Carpentry Sprint at UC Berkeley

The UC Berkeley Library is participating in the worldwide Library Carpentry Sprint happening on June 1st and 2nd, which is a part of the larger Mozilla Global Sprint 2017. Library Carpentry is a part of the Software Carpentry and Data Carpentry family, and it strives to bring the fundamentals of computing, as well as a platform for further self-directed learning in digital scholarship to librarians and library staff. The goal of this Library Carpentry sprint is to improve Library Carpentry lessons, as well as get input from archivists about how we can make our lessons more archivist friendly. That said, you do not need to be a librarian to participate. If you are interested in pedagogy or are familiar with digital tools taught in Library Carpentry workshops, we seek your input in improving Library Carpentry lessons.

This sprint will take place in the Berkeley Institute for Data Science (BIDS), and you can drop by anytime between 9am and 5pm on June 1st and 2nd to help amend, update, and extend the existing Library Carpentry lessons. You can stay as long as you want, whether it be two hours or two days.

Besides improving already existing Library Carpentry lessons, this sprint will also focus on getting draft lessons for SQL, Python, web scraping, and other topics into final shape for launch. Participants can contribute code or content; proofread writing, visual design, and graphic art; do QA (quality assurance) testing on prototype tools or apps; or advise or comment on project ideas or plans. All skill levels are welcome—and needed—as there are many ways to participate. Basically, we want you to bring your own unique perspective to the Library Carpentry lessons.

If you are interested in participating, all the details for the UC Berkeley Library Carpentry event can be found here, and you can sign up on the Library Carpentry Sprint Etherpad, which can be found here. Towards the of the Etherpad you will find the UC Berkeley location. Just add your name under that location, and show up during the sprint.

Hope to see you there!

 

Library of Congress releases 25 million metadata records

The Library of Congress recently released 25 million metadata records for free bulk download at loc.gov/cds/products/marcDist.php. These MARC records make up the foundation for library catalogs, such as OskiCat, which have enabled library users to find and access library books and other media for decades. As the LOC describes the collection:

 

The data covers a wide range of Library items including books, serials, computer files, manuscripts, maps, music and visual materials.  The free data sets cover more than 45 years, ranging from 1968, during the early years of MARC, to 2014.  Each record provides standardized information about an item, including the title, author, publication date, subject headings, genre, related names, summary and other notes.

Reading Room at the Library of Congress

Library of Congress Reading Room, from https://www.loc.gov

The data is available in UTF-8, MARC8, and XML formats, and has been conveniently divided by media type including books, computer files, maps, music, and more.

We’ve added the resource to the public section of the Computational Text Analysis and Text Mining Guide, where you can find many other sources for large-scale text analysis projects. For more information, take a look at the LOC’s Getting Started (PDF) for details on accessing the data.

Go from Analog to Digital Texts with OCR

OCR text

A collection of digitized texts marks the start of a research project —  or does it?

For many social sciences and humanities researchers, creating searchable, editable, and machine-readable digital texts out of heaps of paper in archival boxes or from books painstakingly sourced from overlooked corners of the library can be a tedious, time-consuming process.

Scholars using traditional methodologies may find it advantageous to have a digital copy of their source material, if only to be able to more easily search through it. For anyone who wants to use computational methods and tools, converting print sources to digital text is a prerequisite. The process of converting an image of scanned text to digital text involves Optical Character Recognition (OCR) software. New developments in campus services are providing additional options for researchers who wish to prepare their texts this way.

What resources does UC Berkeley offer to convert scans to digital text?

  • For basic needs, try the Library’s scanners.
  • For documents with complex layouts or for additional language support, ABBYY FineReader with Berkeley’s OCR virtual desktop is a solution.
  • Finally, Tesseract can handle large scale OCR projects.

Books and simple documents: library scanners with OCR software

All of the UC Berkeley libraries, including the Main (Gardner) Stacks, have at least one Scannx scanner station with built-in OCR software. This software automatically identifies and splits apart pages when you’re scanning a book, and it performs OCR on any text it can identify. You can save your results as a “Searchable PDF” (with embedded OCR output) or as a Microsoft Word document, or you can save page images as TIFF, JPEG, or PDF files (omitting digitized text). For book scanning or simple document scanning, the library scanners can take you from analog to digital in a single step.

Complex layouts or language support: ABBYY FineReader and Berkeley Research Computing’s OCR virtual desktop

If your source material has a complex layout (like irregular columns, embedded images, and/or tables that you want to continue to edit as tables) or uses a non-Latin alphabet, ABBYY FineReader OCR may get you better OCR results. FineReader supports Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, and Thai, among other languages.

On campus, FineReader is available on computers in the D-Lab (350 Barrows). From off campus, the OCR virtual research desktop provided through Berkeley Research Computing’s AEoD service (Analytic Environments on Demand, pronounced “A-odd”) allows users to log into a virtual Windows environment from their own laptop or desktop computer anywhere there’s an internet connection. If you’re visiting an archive and aren’t sure that your image capture setup is getting good enough results to use as OCR input, you can log into the OCR virtual research desktop and try out a couple samples, then refine your process as needed. You can also work on your OCR project from home, or on nights and weekends when campus buildings are closed. To use the OCR virtual research desktop, sign up for access at http://research-it.berkeley.edu/ocr.

FineReader is not generally recommended for very large numbers of PDFs because each conversion must be started by hand. However, if you don’t need to differentiate the origin of your various source PDFs (e.g., if your text analysis will treat all text as part of a single corpus, and it doesn’t matter which of the million PDFs any particular bit of text originally came from), you might be able to use FineReader by creating one or more “mega-PDFs” that combine tens or hundreds of source PDFs and letting it run over a long period of time. At a certain point, however, Tesseract might be a better choice.

OCR at scale: Tesseract on the Savio high-performance compute cluster

If you have thousands, hundreds of thousands, or millions of PDFs to OCR, a high-powered, automated solution is usually best. One such option is the open source OCR engine Tesseract. Research IT has installed Tesseract in a container that you can use on the Savio high performance computing (HPC) cluster. For researchers who are less comfortable with the command line, there is also a Jupyter notebook available that provides the necessary commands and “human-readable” documentation, in a form that you can run on the cluster. Any tenure-track faculty member is eligible for a Faculty Computing Allowance for using Savio. For graduate students, talk to your advisor about signing up for an allowance and receiving access.

No matter how large or small your OCR project is, UC Berkeley has the perfect tool for you in scanning equipment, ABBYY FineReader, or Tesseract. Happy converting!

Q & A with Julie van den Hout

Van den Hout, a 2015 graduate from Berkeley, has been a Digital Humanities Project Archivist at the Bancroft since October 2016.  Julie came to Berkeley having discovered her passion for historical research after working for some years in health care. Her honors thesis explored a 17th-century Dutch book aimed at potential immigrants to what is now New York; it was awarded the Charlene Conrad Liebau Library Prize for Undergraduate Research (honorable mention).

What inspires you about your position?
It has been an honor to work with the Engel Sluiter Historical Documents Collection. This immense personal research collection, donated to the Bancroft Library, is truly a legacy of Dr. Sluiter’s life work as a UC Berkeley Latin American History professor and researcher. By bringing together materials from archives worldwide, the collection provides detailed Spanish, Dutch, English, and Portuguese perspectives on sixteenth and seventeenth century Atlantic trade. Through a UC Berkeley Digital Humanities Collaborative Research grant, Dutch Studies and the Bancroft Library are working together to digitize a small subset of the collection on the seventeenth century colony of New Netherland (now New York), and then analyze the texts using natural language processing. Working with the primary sources in the Engel Sluiter Collection has taught me much more than I could ever learn in a classroom. I am excited about the capabilities of digital humanities, and what our current project will reveal about the Dutch colony.

Your priorities over the next 6-9 months
My overarching and ultimate goal with the project is to enhance search capabilities for the Engel Sluiter Collection, and help make these impressive, but relatively unexplored, materials more accessible to researchers. My immediate focus is to reconcile the Dutch documents with the digitized OCR outputs, in preparation for processing using our in-house topic modeling application that will identify themes within the corpus. The documents will be then be published online, with the new search capabilities freely available to researchers worldwide. At the same time, I will be working to learn more about the potential of digital humanities and applying our model to other historical texts.

Opportunities at the Berkeley campus and the Library
The libraries of UC Berkeley are a treasure trove of primary and secondary sources for study of the Atlantic World. Being at a research institution is a great way to find support for new ideas, and digital humanities at UC Berkeley is at the cutting edge in its field. While some people see digital humanities as trying to replace traditional scholarship, I see it as being able to enhance and partner with traditional scholarship to add new dimensions or perspectives. In our project, for example, the use of technology is helping us find connections in the historical data and texts that may not readily visible in traditional formats.

A favorite book or favorite campus hangout
My favorite book is Two Years Before the Mast, by Richard Henry Dana, Jr., Dana’s own memoir of two years spent, as an ordinary sailor, on a merchant ship between Massachusetts and California around Cape Horn, in the early 1800’s. Long before I became interested in academic history, Dana’s engaging accounts of life at sea and trading hides along the Pacific Coast brought the past to life for me. His descriptions of colorful, pre-gold rush Mexican California opened my eyes to a California I had never learned in history books.

Gallica Gives

"Ça, mon enfant, c'est du pain.. [That, my child, is bread...]" par Gottlob in L'Assiette au beurre (1901)

Online since 1997, Gallica remains one of the major digital libraries available for free on the Internet. With more than 12 million high-resolution digital objects from the collections of the Bibliothèque Nationale de France (BnF) as well as from hundreds of partner institutions, it includes books, journals, newspapers, manuscripts, maps, images, audio files, and more. The illustration above “Ça, mon enfant, c’est du pain.. [That, my child, is bread…]” by Fernand-Louis Gottlob was published in one of the first issues of the weekly satirical magazine L’Assiette au beurre (1901-1936) which is also held in print at UC Berkeley. Committed to the ever-evolving needs of its user community, Gallica’s social media outlets include Facebook, Twitter, Pinterest and even a BnF app.

Where to Find the Texts for Text Mining

Text mining, the process of computationally analyzing large swaths of natural language texts, can illuminate patterns and trends in literature, journalism, and other forms of textual culture that are sometimes discernible only at scale, and it’s an important digital humanities method. If text mining interests you, then finding the right tool — whether you turn to an entry-level system like Voyant or master a programming language like Python — is only a part of the solution. Your analyses are only as strong as the texts you’re working with, after all, and finding authoritative text corpora can sometimes be difficult due to paywalls and licensing restrictions. The good news is the UC Berkeley Libraries offer a range of text corpora for you to analyze, and we can help you get your hands on things we don’t already have access to.

The first step in your exploration should be the library’s Text Mining Guide, which lists text corpora that are either publicly accessible (e.g., the Library of Congress’s Chronicling America newspaper collection) or are available to UCB faculty, students, and staff (e.g., JSTOR Data for Research).  The content of these sources are available in a variety of formats: you may be able to download the texts in bulk, use an API, or make use of a content provider’s in-platform tools. In other cases (e.g., ProQuest Historical Newspapers), the library may be able to arrange access upon request. While the scope of the corpora we have access to is wide, we are particularly strong in newspaper collections, pre-20th century English literature collections, and scholarly texts.

What happens if the library doesn’t have what you need? We regularly facilitate the acquisition of text corpora upon request, and you can always email your subject librarian with specific requests or questions. The library will deal with licensing questions so you don’t have to, and we’ll work with you to figure out the best way to make the texts available for your work, often with the help of our friends in the D-Lab or Research IT . We also offer the Data Acquisition and Access Program to provide special funding for one-time data set purchases, including text corpora.  Your requests and suggestions help the library develop our collection, making text mining easier for the next researcher who comes along.

Important caveats:

  • Unless explicitly stated, our contracts for most Library databases and library resources (e.g., Scopus, Project MUSE) don’t allow for bulk download. Please avoid web scraping licensed library resources on your own: content providers realize what is happening pretty quickly, and they react by shutting down access for our entire campus. Ask your subject librarian  for help instead.
  • Keep in mind that many of the vendors themselves are limited in how, and how much access, they can provide to a particular resource, based on their own contractual agreements. It’s not uncommon for specific contemporary newspapers and journals to be unavailable for analysis at scale, even when library funding for access may be available.
